Abstract
- The use of simple 2,5-diamidopyrrole derivatives as anion receptors has been investigated. Reaction of 3,4-diphenylpyrrole-2,5-dicarboxylic acid chloride with n-butylamine or aniline has produced two new amidic cleft anion receptors 1and 2. The anion-coordination ability of these species has been determined by 1H NMR titration techniques. Crystal structures of 1and 2have been elucidated, revealing a continuous hydrogen bonding network formed by 1and dimerization of 2via NH⋯O and CH⋯O hydrogen bonds.
